The only bad habit you get is putting a foot down to get your balance back.....
I don't put my foot down, but rather stick it out for balance. That's all I REALLY did on the dirt bike too. Stick it out like an outrigger... I still do that once in a while. The only time I ever stab the ground with it is when I am BARELY moving and need to to not fall over. Other than that, my feet are on pegs.
